Algebraic Manipulation of Boolean Expressions
You can transform one
boolean expression into an equivalent expression by applying the postulates the theorems of boolean algebra. This is important if you
want to convert a given expression to a canonical form (a
standardized form) or if you want to minimize the number of literals (primed or unprimed variables) or terms in an
expression. Minimizing terms and expressions
can be important because electrical circuits often consist of individual components that implement each term or literal for a given expression.
Minimizing the expression allows the designer to use fewer
electrical components and, therefore, can reduce the cost of the system.
